Abstract:Pretensioned precast concrete girders are mainly designed to resist high bending moments. Although limited shear forces act on these girders, a minimal amount of web reinforcement
should be added in order to meet design code requirements. Since the cutting, bending and placing of stirrups is a labour-intensive job, a possible alternative can be the replacement of
stirrups by adding fibres to the concrete. By using steel-fibre-reinforced concrete (SFRC), the production process of precast elements can be shortened and costs reduced significantly. In
order to investigate the shear capacity of full-scale prestressed fibre-reinforced concrete elements, an experimental programme was carried out on 20 m span precast girders.
Additionally, standard prisms were cast from the same concrete batch to derive the postcracking behaviour of the SFRC. The ultimate shear capacity of all the girders is evaluated
with respect to the current shear design provisions for SFRC according to the fib Model Code for Concrete Structures 2010.
